Figure 9.

Exercise stress, controls vs. patients. Correlation between the heart rate and the systolic (pink symbols) and diastolic (black symbols) times is displayed by error bar charts plotting the standard deviations of individual variables at each 5 beats heart rate increase during stress. Repeated-measures analysis of variance (ANOVA) was used to compare data groups. At each stage of stress inter-group comparison was performed and significant differences (p < 0.05) are displayed with symbols: * = significant differences between controls (NL, left upper panel) and patients groups.
